Specification of Letters Patent.

Application filed October 1;, 1910. Serial No. 587,035.

'To all whom it may concern:

Be it known that I, STANisLAw Knanzs, a sub'ect of the Czar of Russia,and residentof arsaw, Russia, have invented a certain new and usefulImprovement in Inverted Burners, of which the following is a speciflcation.

The rapidity with which the metal parts of inverted burners contacted bythe combustion gases are destroyed has required that such parts as themixing tube, the casing and the deflector should be formed of refractorymaterial.

The present invention relates to an improved construction of invertedburner in which the 'diificulties of connecting separate piecesproduced-from ceramic material in a reliableimanner are avoided inthiswise, namely, the parts 'in. question, such as the mixing tube, thecasing and the. deflector, of

refractory material, each consist only of a single piece. By simplyscrewing the nozzle into the mixing tube, all of the parts aresimultaneously rigidly connected with one another, the correctadjustment being obtained by suitable formation of the parts.

A feature of this invention is the simple formation of the parts,permitting them to be connected in simple manner. This style ofconnection ma naturally also be used in "burners formed rom materialwhich is not of refractory nature.

' by which it-is. su

The accompanying drawing shows one form of the invention partly insection and partly in elevation.

The ceramic fitting comprises the inner mixing tube a, the casing b andthe deflector c crowning the mixing tube;

The lower ortionpf the mixing tube a is 1 "ovided with lugs 03 servingto support the 'mautleholder. At the upper end the wall of the tube ismade of increased section, and is )royided on the inner side with ascrew ihread into which is threaded the nozzle bringin all the partstogether. On the outer side of the portion of increased thicknessareprovided, radial arms 1 which serve to cgn'nect the mixing tube awith the cats mg The casing 12 surrounding the mixing tube is formed atits upper end w th a flan e ported on the arms f o the mixing tube. .;Te lower edge of the casing is also provided with a flange, or isotherwise arranged for attachment of the burner globe.

The mixing tube is advantageously of conical formation at its upper endso as to fit the deflector c, the adjacent end of which iscorrespondingly shaped. The deflector is provided at its lower end withseveral, for example three, radial projecting parts i, which, when theburner is assembled bear on the upper edge 9 of the casing b and thusmaintain the parts in proper relative position. The deflector c isformed at m with a tongue which fits in groove-n in the mixing tube aand prevents relative rotation of the deflector c and th mixing tube.

The deflector prevents entrance into the regulatablc air inlet openingsA: from below.

On assembling the parts the mixing tube a corresponding a is firstintroduced into the casing b so that the arms) bear on the flange 9.Thereupon the deflector is placed on the mixing tube a in suchmannerthat the arms i rest on the edge of the flange g, the tongue mfits into the groove 71, and the nozzle piece e is then connected withthe whole by screwing it into the mixing tube. nozzle then presses onthe inner side of the deflector and in consequence clamps together thethree ceramicelements a, b and c of the fitting.

The heated products of combustion rise inside the globe attached to-thecasing, 'be tween the radial arn'is-formed on themixing tube, pass outof the casing, come in contact with the deflector, and on account of theinclined surfaces of the latter are guided outward without coming incontact with the metal nozzle piece and the gas supply pipe. This formof deflector also insures the supply of pure air for combustion to theair inlet openings of the nozzle. In the-Bunsen tube, which is formed ofmetal, is inserted a small roll of gauze whereby on the burner beinglighted, ignition in the nozzle is prevented.

Having described my invention what I claim and desire to secure byLetters Patent of the United States is 1. An inverted burner comprising,in combination with a mining tube having a to fit therein, a casing anda deflector, radial arms on said mixing tube, a flange on said casingadapted to be supported by said arms and arms on said deflector adaptedto bear on said flange,

as and for the purpose set forth.

A flange Z on the threaded socket and "a nozzle piece adapted 2. Aninverted burner comprising in comination with: a mixing tube having v aMinnd socket and a nozzle piece adapted to fit therein; :1 casing and adeflector, radiui arms on said mixing tube, a flange on said casingadapted to he supported by said arms, arms on said deflector adapted tobear,

arms on said mixing tube, a flange on said casing adapted to besupported by sald arms, arms on said deflector adapted to bear on saidflange, a groove in said mixing tube, a tongue on said deflector adaptedto enter 20 said groove, and a flange on said nozzle piece adapted tocontact with said deflector, as zind for the purpose set forth.

. In testimony whereof I have signed my name to this specification inthe presence of 25 two subscribing witnesses.
